Patent number: 6545058Abstract: The present invention provides an ophthalmic composition for soft contact lenses (SCL), which contains a terpenoid as an active ingredient, an ophthalmic composition for SCL, which contains polyoxyethylene sorbitan ester, a method of enhancing the wettability of soft contact lenses, which comprises bringing terpenoid into contact with SCL and a method of inhibiting adsorption of terpenoid onto SCL, which comprises adding polyoxyethylene sorbitan ester to an ophthalmic composition containing a terpenoid. The ophthalmic composition containing a terpenoid improves, for example, the wettability of SCL, thereby to inhibit decrease in the water content of SCL. As a result, it can inhibit a dry feeling and an uncomfortable feeling during wearing SCL and is useful for enhancing the wettability of SCL. Further, addition of polyoxyethylene sorbitan ester leads to the inhibition of adsorption of terpenoid onto SCL.Type: GrantFiled: February 24, 2000Date of Patent: April 8, 2003Assignee: Senju Pharmaceutical Co., Ltd.Inventors: Koji Doi, Hisayuki Nakayama, Takuya Nakajima, Noriko Sakai
